and a spiral conveyor 11.1 on the immature grain receiving trough 10.
2 installed horizontally. Thus, a grain sorting section 13 is provided adjacent to the hulling room 2. Inside the grain sorting section 13, rotary separators 14 and 15 are horizontally installed in upper and lower stages in a freely rotatable manner.

16 is a rotating drum of the upper rotary separator 14, and the rotating drum 16 has a large number of pot holes 17 on its inner surface as shown in FIG. At the center of the rotating drum 16, there is provided a mixed rice collection spiral receiving trough 18 having a substantially U-shaped cross section. 19
is a spiral conveyor installed horizontally on the mixed rice collection spiral receiving trough 18. Adjustment plate 2 attached to mixed rice recovery spiral catch trough 18
0.21 is installed separately into the supply section 22 and the discharge section 23.

The adjustment plate 20 attached to the supply section 22 is rotated by the detection plate 25 attached to the mixed rice collection spiral receiving trough 18. That is, as shown in FIG. 3, a protrusion 24 is attached to the mixed rice collection spiral receiving trough 18,
An L-shaped lever 26 with a detection plate 25 attached to the protrusion 24 is pivoted 27, and an arm 28 of the adjustment plate 20 is pivoted 29 to the L-shaped lever 26. Reference numeral 30 denotes a spring that constantly rotates the rotating drum 16 in the upward direction. In the embodiment shown in FIG.
This is an embodiment in which a scraping plate 36 serving as a souffle bar is attached to the surface layer 32 of the holder.

In this way, the scraping plate 36 scrapes off excess grains, so that the supply section 22 is also averaged. In the case of FIG. 5, a funnel 33 is attached to the inside of the adjustment plate 21 attached to the mixed rice collection spiral receiving trough 18. The bottom plate 34 of the funnel 3-3 is made of a perforated plate, through which the brown rice passes.

A return passage 35 is formed in the lower end portion, and
A drop opening 37 is formed in the scraping plate 36. 38 is a stop plate. FIG. 6 shows another embodiment in which the stop plate 38 attached to the lower side of the drop port 37 is not included.
The figure shows a perspective view of FIG. 39 is a fried grain thrower
140 is a supply funnel, and 41 is a paddy/rice return gutter.

Next, we will discuss the effect.

First, when the raw material paddy is supplied to the loading hopper l, the raw material paddy flows down and flows into the hulling chamber 2, is hulled by the hulling roll 3.3, falls on the downflow gutter 5, and is then flowed down into the hulling chamber 2. 4. In the wind selection chamber 4, suction air is blown by the action of the suction fan 6, so that the first rice husk is discharged from the discharge port 8 through the discharge pipe 7. The immature grains advance a little by the suction wind, flow into the immature grain receiving trough 10, and are taken out by the conveyor 12. The mixed rice of unhulled brown rice and structured paddy rice flows into the mixed rice receiving trough 9 and is supplied to the grain thrower 39 by the conveyor 11 on the rice receiving trough 9. feed funnel 40. Then, it is supplied from the supply funnel 40 to the upper rotating drum 16, and is stirred by the rotation of the rotating drum 16. Then, based on a well-known theory, brown rice, which has a heavy specific gravity, sinks to the bottom layer, and unhulled rice, which has a light specific gravity, rises to the top. Therefore, the brown rice that has sunk to the lower layer and a portion of the unhulled rice that has floated to the upper layer are scooped up by the pot hole 17 formed on the inner surface of the rotating drum 16 and taken out to the mixed rice recovery spiral receiving trough 18, and the mixed rice recovery spiral It is transported laterally by the helical conveyor 19 of the receiving trough 18 and is supplied into the rotary drum 43 of the rotary separator 15 located below the drop port 42 thereof. As mentioned above, in the upper rotary drum 16, not only brown rice but also some unhulled rice is scooped up through the pot hole 17, so all that remains in the rotary drum 16 is unhulled rice.
This is discharged from the paddy/rice return gutter 41 on the discharge side and returned to the loading hopper l.

Reprocessed. The mixed rice supplied to the lower rotary drum 43 is scooped up through the pot hole 17, and only the most settled brown rice is taken out to the brown rice collection spiral receiving trough 44, where it is taken out as finished rice.

However, as described above, more mixed rice is distributed on the supplying section 22 side than on other parts, and the separation state changes if left as is. However, in the present invention, the adjustable plates 20 and 21 are attached to the supply section 22 and the discharge section 23 of the rotary drum 16, respectively, so that the attachment angles of the adjustment plates 20 and 21 can be adjusted individually. By adjusting the adjustment plate 21 according to the condition of the lower layer of sunken grain scooped up by the pot hole 17 formed on the inner surface of the rotating drum 16, a good number of grains can be collected.

In addition, in the case of FIG. 5, the surface layer of the grains 31 in the supply section 22 is scraped by the scraping plate 36 protruding from the mixed rice collection spiral receiving trough 18 to the inner surface of the rising side of the rotating drum 16, as if it were a scraper. The grains in the supply section 22, which tend to be large, are averaged to be the same as the grains in the discharge section 23.

Sort well.

Further, in the case of FIG. 5, since a funnel 33 is provided inside the supply section 22 of the mixed rice collection spiral receiving trough 18, the grains received by the funnel 33 are sent to the return passage 35 and the drop opening 37. The oversupply of the supply section 22 is further averaged out as it is returned to the rotating drum 16 through the supply section 22 .

As described above, the present invention includes a hulling chamber 2, a substantially U-shaped collection spiral receiving trough 18 inside, and scooping up sorted grains through a pot hole 17 formed on the inner surface to separate hulled paddy rice and hulled brown rice. In a hulling device that separates the rotary separators 14 and 15 for sorting mixed rice from the sunken grain sorting section 13, the approximately U-shaped collection spiral of the grain sorting section 13 consisting of the rotary separators 14 and 15 is used. The adjustment plate 20 attached to the receiving gutter 18 is connected to the supply section 22 and discharge section 23 of the rotary separator 14.15.
A rice hulling device using a rotary separator divided into two parts, and an adjustment plate 2 of the substantially U-shaped collection spiral receiving trough 18.
A part of the rotary separator 14, 15 is provided on the adjusting plate 20 so as to be freely undulating, and the rotating drum 16 of the rotary separator 14, 15 is provided on the adjusting plate 20.
．． A rice hulling device using a rotary separator, which is equipped with a detection plate 25 on which the falling grains of the scooped grains come into contact with the inner surface of the rice cracker 43 and is automatically adjusted; A hulling device using a rotary separator is attached to the collection spiral receiving trough 18, and a scraping plate 36 is attached to the inner surface of the rotating drum 16.43 of the rotary separator 14.15 to serve as a souffle bar against the surface layer 32 of the grain scooped up. A return passage 35 is formed in the substantially U-shaped collection spiral receiving trough 18 for returning the grains scooped up on the inner surface of the rotating drum 16.43 of the supply section 22 of the rotary separator 14.15 to the rotating drum 16.43. Since the hulling device uses a rotary separator, the amount of grains in the supply section 22, which is very large, is transferred to the discharge section 23 and is averaged, thereby achieving the effect of good sorting.
